Project Labor Agreements. Building and construction trades workers are one of the hardest hit groups in the nationâs job crisis. Yet state lawmakers, backed by construction industry CEOs, want to cut the wages of those workers by eliminating prevailing wage laws and project labor agreements (PLAs) on public construction projects.
There are many algorithms to solve scrambled Rubik's Cubes. The maximum number of face turns needed to solve any instance of the Rubik's Cube is 20, and the maximum number of quarter turns is 26. These numbers are also the diameters of the corresponding Cayley graphs of the Rubik's Cube group. An algorithm that solves a cube in the minimum number of moves is known as God's algorithm. There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. The second is to count the number of face turns.
Make a Cross on the Top Layer. If you have already solved the first layer, you can skip to Step 2. Otherwise, hold your Rubik's Cube with the yellow center piece facing up. Find the yellow & green piece and move it to the green side, the side that is green in the center.Twist the green side 1 or 2 quarter-turns to move the yellow & green piece to the top. Your Rubik's Cube should look like this:If the two colors don't match up, flip the yellow & green piece like this: Solve the other 3 sides the same way so you have a yellow cross on top. You won't mess it up if you use the bottom layer to move pieces around. Watch the video at the top if you get stuck.therwise, hold your Rubik's Cube with the yellow center piece facing up. Find the yellow & green piece and move it to the green side, the side that is green in the center. Twist the green side 1 or 2 quarter-turns to move the yellow & green piece to the top. Your Rubik's Cube should look like this:
